Then, how far should smoke detector be placed from ceiling?

If this is not possible, install the Smoke Alarm at least 4 inches (102 mm) from the wall or corner. For wall mounting (if allowed by building codes), the top edge of Smoke Alarms should be placed between 4 inches (102 mm) and 12 inches (305 mm) from the wall/ceiling line, below typical “dead air” spaces.

This means that if you have a four-bedroom house, and all of the bedrooms are accessed from a second-floor hallway, you need to have a smoke detector in each bedroom and one in the hallway outside the bedrooms. One smoke detector must be present on every floor of the house, including basements and attics.

What is the difference between photoelectric and ionization smoke detector?

One is a “fast flame” fire, the other is for smoldering fires. In tests, ionization alarms will typically respond about 30 to 90 seconds faster to “fast-flame” fires than photoelectric smoke alarms. However, in smoldering fires ionization alarms respond an average of 15 to 50 minutes slower than photoelectric alarms.

Where should I put a carbon monoxide alarm?

If you live in a multi-story home, be sure to place at least one carbon monoxide detector on each level. If your furnace is located in the basement, be sure to place a CO detector there, as well. Likewise, if you have a gas clothes dryer, put an alarm in the laundry room.

2

Do carbon monoxide fumes rise or fall?

CO is slightly lighter than air. The difference is so slight that CO is found to evenly distribute itself indoors. It is worth mentioning that CO indoors is usually generated from incomplete combustion (heat source) and therefore traveling in a warm air stream. Warm air is more buoyant and does rise.

3

Where should CO detectors be located?

According to the carbon monoxide guidelines of the National Fire Protection Association (NFPA 720, 2005 edition), all carbon monoxide alarms “shall be centrally located outside of each separate sleeping area in the immediate vicinity of the bedrooms,” and each alarm “shall be located on the wall, ceiling or other

5

Can you get carbon monoxide poisoning from a heater?

Carbon monoxide is produced by devices that burn fuels. Therefore, any fuel-burning appliance in your home is a potential CO source. Electrical heaters and electric water heaters, toasters, etc., do not produce CO under any circumstances.

6

What can cause carbon monoxide poisoning?

Household appliances, such as gas fires, boilers, central heating systems, water heaters, cookers, and open fires which use gas, oil, coal and wood may be possible sources of CO gas. It happens when the fuel does not burn fully. Running a car engine in an enclosed space can cause CO poisoning.

7

Is co heavier or lighter than air?

= incorrect Carbon monoxide is not heavier than air - in fact it is slightly lighter as CO has the RMM of 28 whereas air is slightly more than this. It is therefore almost neutral density. However in a normal room, thermal convection current dominate transport of gases in a room.

8

What is the best carbon monoxide detector?

Kidde KN-COPP-B-LPM. This digital carbon monoxide alarm is a popular choice on Amazon—number three out of all CO detectors. It's equipped with the best sensor in the industry, an electrochemical sensor, to help detect carbon monoxide in your home.

How long is a carbon monoxide detector good for?

But CO alarms do not last forever. The detecting components will lose their effectiveness after 5 to 7 years and may no longer detect carbon monoxide. First Alerts website states: “After 5 years any detector should be replaced with a new CO alarm.” COSTAR recommends replacing their CO alarms every 6 years or sooner.

10

How many smoke detectors do you need in your house?

Answer: The National Fire Protection Association recommends homes should have smoke alarms installed inside every bedroom, outside each sleeping area and on every level of the home, including the basement. So that means a 2 story, 3 bedroom house needs a minimum of five smoke alarms.

11

What is a carbon monoxide detector used for?

A carbon monoxide detector or CO detector is a device that detects the presence of the carbon monoxide (CO) gas in order to prevent carbon monoxide poisoning. CO is a colorless, tasteless and odorless compound produced by incomplete combustion of carbon-containing materials.

12

How many carbon monoxide detectors should you have in your house?

They should be installed specifically outside of each sleeping area in a house (there could be multiple areas), on each level of the house and in the basement also. You may only need one carbon monoxide detector in your house, but you could need several detectors depending on the layout of your home.

13

Is carbon dioxide more or less dense than air?

Carbon dioxide, also known by the chemical formula CO2, has a higher density than the other gases found in air, which makes CO2 heavier than the air. Air is composed of approximately 78 percent nitrogen, 21 percent oxygen, and less than 1 percent of other gases.

14

What is carbon monoxide and how is it produced?

Carbon monoxide is a by-product of combustion, present whenever fuel is burned. It is produced by common home appliances, such as gas or oil furnaces, gas refrigerators, gas clothes dryers, gas ranges, gas water heaters or space heaters, fireplaces, charcoal grills, and wood burning stoves.

15

How does co harm you?

Carbon monoxide is harmful when breathed because it displaces oxygen in the blood and deprives the heart, brain, and other vital organs of oxygen. Large amounts of CO can overcome you in minutes without warning—causing you to lose consciousness and suffocate. CO poisoning can be reversed if caught in time.

16

How can we protect ourselves from carbon monoxide poisoning?

To protect against carbon monoxide poisoning, the CDC recommends that heating systems that have chimneys be checked by a technician every year. Make sure gas appliances are vented properly and never use a generator, camp stove or oven as a heater indoors.

17

How can you avoid carbon monoxide poisoning at home?

Replace your CO detector every five years. Have your heating system, water heater, and any other gas, oil, or coal burning appliances serviced by a qualified technician every year.
